RegexMatchTuple

Specifies where in a web request to look for the RegexPatternSet.

The RegexPatternSetId for a RegexPatternSet. You use RegexPatternSetId to get information about a RegexPatternSet (see GetRegexPatternSet), update a RegexPatternSet (see UpdateRegexPatternSet), insert a RegexPatternSet into a RegexMatchSet or delete one from a RegexMatchSet (see UpdateRegexMatchSet), and delete an RegexPatternSet from AWS WAF (see DeleteRegexPatternSet). RegexPatternSetId is returned by CreateRegexPatternSet and by ListRegexPatternSets.

Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on RegexPatternSet before inspecting a request for a match. You can only specify a single type of TextTransformation. CMD_LINE When you’re concerned that attackers are injecting an operating system commandline command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations: Delete the following characters: \ “ ‘ ^ Delete spaces before the following characters: / ( Replace the following characters with a space: , ; Replace multiple spaces with one space Convert uppercase letters (A-Z) to lowercase (a-z) COMPRESS_WHITE_SPACE Use this option to replace the following characters with a space character (decimal 32): \f, formfeed, decimal 12 \t, tab, decimal 9 \n, newline, decimal 10 \r, carriage return, decimal 13 \v, vertical tab, decimal 11 non-breaking space, decimal 160 COMPRESS_WHITE_SPACE also replaces multiple spaces with one space. HTML_ENTITY_DECODE Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations: Replaces (ampersand)quot; with ” Replaces (ampersand)nbsp; with a non-breaking space, decimal 160 Replaces (ampersand)lt; with a “less than” symbol Replaces (ampersand)gt; with > Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh;, with the corresponding characters Replaces characters that are represented in decimal format, (ampersand)#nnnn;, with the corresponding characters LOWERCASE Use this option to convert uppercase letters (A-Z) to lowercase (a-z). URL_DECODE Use this option to decode a URL-encoded value. NONE Specify NONE if you don’t want to perform any text transformations.
